Some cases just don't leave enough space around the Dock Connector to enable you to use your favorite accessories, so CableJive has released dockStubz ($23), a 1.3-inch add-on that's designed to restore the missing functionality. One end has a female Dock Connector, the other a male Dock Connector, so you can plug your iPhone, iPod, or iPad in and connect oversized cables, FM transmitters, and the like without issues -- unless, of course, the device isn't compatible with the accessory in the first place. Even then, CableJive includes a feature that's capable of converting old FireWire charging accessories to be capable of charging USB-only devices. Expensive as a workaround, dockStubz is nevertheless one of the very rare accessories capable of extending Apple's bottom accessory ports.
